template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< int, P > | bitCount (vecType< T, P > const &v)
| Returns the number of bits set to 1 in the binary representation of value. More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< T, P > | bitfieldExtract (vecType< T, P > const &Value, int Offset, int Bits)
| Extracts bits [offset, offset + bits - 1] from value, returning them in the least significant bits of the result. More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< T, P > | bitfieldInsert (vecType< T, P > const &Base, vecType< T, P > const &Insert, int Offset, int Bits)

template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< T, P > | bitfieldReverse (vecType< T, P > const &v)
| Returns the reversal of the bits of value. More...
template<typename genIUType >
GLM_FUNC_DECL int | findLSB (genIUType x)
| Returns the bit number of the least significant bit set to 1 in the binary representation of value. More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< int, P > | findLSB (vecType< T, P > const &v)
| Returns the bit number of the least significant bit set to 1 in the binary representation of value. More...
template<typename genIUType >
GLM_FUNC_DECL int | findMSB (genIUType x)
| Returns the bit number of the most significant bit in the binary representation of value. More...
template<typename T , precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< int, P > | findMSB (vecType< T, P > const &v)
| Returns the bit number of the most significant bit in the binary representation of value. More...
template<precision P, template< typename, precision > class vecType>

| Multiplies 32-bit integers x and y, producing a 64-bit result. More...
template<precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL vecType< uint, P > | uaddCarry (vecType< uint, P > const &x, vecType< uint, P > const &y, vecType< uint, P > &carry)
| Adds 32-bit unsigned integer x and y, returning the sum modulo pow(2, 32). More...
template<precision P, template< typename, precision > class vecType>
GLM_FUNC_DECL void | umulExtended (vecType< uint, P > const &x, vecType< uint, P > const &y, vecType< uint, P > &msb, vecType< uint, P > &lsb)
| Multiplies 32-bit integers x and y, producing a 64-bit result. More...
